SPECIEIGATIQN forming part of Letters Patent No. 639,403, dated DecemberApplication filed October 31, 1898. Serial No. 695,071. (No model.)

To whom it may concern.-

Be it known that I, GEORGE ONNO Hon- FELD KLOPP, a subject of the Queenof Great Britain and Ireland, residing at Chelsea, London, England, haveinvented Improvements in Cocks or Taps, of which the following is aspecification.

Cocks or taps (hereinafter called taps have heretofore been constructedwith ballvalves working against an annular seatof elastic material, suchas india-rubber, and opened by an endwise-movable spindle; but all suchprevious constructions, so far as I am aware, possess many seriouspractical disadvantages, being costly to construct, difficult tomaintain in a fluid-tight condition, liable to distortion and rapid wearof the valve-seat, and difficult to repair while under pressure.

This invention relates to an improved construction of tap that is verysimple and cheap to construct and very efficient and durable in use.

In the accompanying drawings, Figure 1 shows in central vertical sectiona tap c011- structed according to my invention, the tap being shownopen. Fig. 2 shows the same tap when closed. Figs. 3, 4, and 5 representa plan, section, and front View, respectively, of a clamp-ring,hereinafter referred to.

The tap, which is of the well-known valve bib-tap pattern, is formedwith two chambers orpassagesviz., an outlet+chainberA and aninlet-chamber B. In the inlet-chamber B, directly below a spindle O andin the open space B, I place a ball D, made of some hardnon-compressible or not easily compressible material-such,for example,as metal. I find in practice that a hollow metal ball capable offloating in water or other fluid may advantageously be used. Thisball 1) when the tap is open lies in the cup of the screw-cap E, whichforms the lower portion of the space B, in which the metal ball works. Iuse a screw cup-shaped cap, as in some forms of tap at present in use,as it enables me to remove the ball easily when necessary. I

In casting the tap an aperture is left in the diaphragm between thechambers or passages A and B, and on the upper side of a shouldersurrounding this aperture that is in the chamber A there is placed anindia-rubber or other suitable ring or washer F, that serves as a seatfor the ball D. The ring or washer F, which is inserted through thechamber A, is secured in. position by a loose clamp-ring ordistance-piece G, having an aperture G on one side to permit of the flowof liquid through the tap. The clamp-ring is also inserted through theupper or outlet chamber A and is held in position laterally by a keyH inthe outer casting, which fits into a keyway H in the clam p-ring. (SeeFig. 3.) When the stuffing-box L, hereinafter referred to, is screweddown into the outlet-chamber A, the clampring G is forced downwardthereby and held perpendicularly, thus firmly retaining the washer orring I in position, and as the clampriug is prevented from rotating thescrewing in of'the stuffing-box L will not produce any twisting ordistortion of the seat-ring F. This method of introducing and securingthe seating is a most important feature of my in vention, as I havefound in practice that a ring inserted and secured by projections be lowthe aperture and between the two chambers becomes dislodged or forcedout of shape under high pressure, thus causing an escape of fluid. Inthe outlet chamber or passage A, I place a spindle C, as in formerconstructions of taps. The spindle O is attached to the screw-spindle Iand is forced down through the aperture between the two chambers andraised by means of the screw when the handle J at the top is rotated. Inorder to minimize friction against the ball D, I may attach to the faceof the spindle O asmall con vcnientlyshaped pad of suitable material,such as indiarubber. At a suitable distance below the crutch or handle Jon the screw-spindle I there is placed or formed a ring K to limit thedistance that the spindle can be screwed down. An ordinary stuffing-bonL L, with stuffing M, is screwed into the top of the tap, as shown, tosecure .the screw-spindle I and the clamp-ring G in position and toprevent leakage. The ball D is made large enough to prevent its passingthrough the aperture formed in the tap between the two chambers A and B,so that the ring or washer F can be replaced by a new one without havingto cut off the supply of water to the tap, the ball at 7 this timeseating itself against the metal edge of the aperture.

Upon water or other liquid being introduced to the chamber or passage Bunder pressure the ball D rises from the cup in the screw-cap E into thespace 13 toward the aperture between the two chambers and is there keptin position against the rubber or other ring or seat F by the pressureof the liquid and in this way closes the tap.

To open the tap, the spindle O is screwed down, so as to force the balltoward the cup in the screw-cap E, and thereby open the aperture betweenthe chambers and permit the water or other liquid to flow through thetap.

As will be seen, the improved cock is very simple in construction, theelastic valve-seat F is held firmly in place without liability of itsbeing distorted by the means employed for fixing it in place or of beingdislodged or forced out of shape byliquid under high pressure'incontacttherewith, and the said seat can be readily inserted and fixed in placeor removed while liquid under pressure is with in the chamber 13.

:What I claim is- 1..Acock or tap comprising a body formed with aninletchamber having a dischargeaperture, a ball-valve located in theinletchamber and of such a size that it cannot pass through thedischarge-aperture, a ring chamber and of such asize that it cannot passthrough the discharge-aperture, an elastic ring or washer held inposition by a non-rotatable clamp-ring within the said aperture so as toserve as a valve -seat and means whereby the said ball can be forcedfrom its seat against the pressure of the fluid, substantially asdescribed. v I

3. A cock or tap comprising a body formed with an inlet chamber having adischargeaperture, an elastic washer held upon the discharge side ofsaid aperture by a non-rotatable clamp-ring, said elasticwasherprojecting beyond the edges of said aperture and serving as a valve-seatfor a ball-valve Within said inlet-chamber, substantially as described.

4. In a cook or tap the combination of a body formed with inlet andoutlet chambers, v

a diaphragm separating said chambersand.

having an aperture therethrough, a ball-valve located within said inletchamber and of such a size that it cannot pass through said aperture, anelastic Washer within said aperture, a clamp-ring pressing against. saidclass tic washer and formed with a keyway, a key on said body engagingsaid keywayand hold- H ing said clamp-ring immovable and a stuffingboxadaptedto force down and hold said non-1 rotatable clamp ring,substantially as described. v p Signed at 2 Popes Head alley, Oornhill,in the city of London, this 7th day of July, 1898.
